Ali was sitting at her desk in the front of the room. On the board was the day’s lesson. Once students would come in she will go more in-depth—if they have questions that is.
Divination is magic which attempts to foresee future events. Many in the wizarding world consider this branch of magic to be imprecise at best. There are several types of Divination. The most imprecise is what is commonly known as "fortunetelling," The second kind of Divination is what is practiced by the centaurs.
The third type of Divination is called Seeing. This is true Divination, although what the Seer reveals is usually in the form of a Prophecy which then itself requires some interpretation. A Seer, one who possesses the Inner Eye, doesn't seem to have control over their Seeing. True Seeing is very rare, but it has happened plenty of times over the centuries. There is a huge cathedral-sized room of the Department of Mysteries where records of thousands of Prophecies are stored in glass spheres. Each sphere is labeled with the initials of the Seer who spoke the Prophecy and the person it was spoken to and with the subject of the Prophecy
Occlumency is the art of magically defending the mind against external penetration, sealing it against magical intrusion and influence - the defensive counter to Legilimency. A practitioner of Occlumency is referred to as an Occlumens. Occlumency is a necessary prerequisite to defeat a Legilimens' lie-detector abilities without suspicious behaviour such as avoiding face-to-face contact and eye contact. Elementary Occlumency involves clearing the mind of thought and emotion, so that the Legilimens can find no emotional ties to memories that the target wishes to conceal. Simple resistance to attack requires similar skills to those needed to resist the Imperius Curse. In its more advanced form, Occlumency allows the user to suppress only feelings and memories that contradict what the user wishes a Legilimens to believe, thus allowing the Occlumens to lie without self-betrayal. This is not practiced at school.
